This invention dispensing machines, and

particularly to machines for dispensing actuation of a customer operatedmeans.

Another object is to provide a machlne of this character which will,upon actuation of a plunger or push-rod, place a drinking I cup in,position to receivey the liquid, and

subsequently deliver Athe charge of liquid into the cup.

Another object is to provide, in a machine of this character, a vchargemeasuring device, in association with a liquid container,.

which will effectively .prevent leakage of the liquid from thecontainer, when in liquid receiving position, or when in chargedelivering position. Y

Other objects and advantages will be apparent from the followingdescription when taken in connection with the accoman ing drawingsf p1151r vthe drawings:

Figurev 1 is a top planview of the oper-- ating mechanism 1n normalposition.

Figure 2 is a front elevatlon of. the same.V Figure a .verticallongitudinal -sectional viewon the line 3-3 of 'Figure-,1;

Figure 4 is a vertical longitudinal sectional view on the line 4 4 ofFigure 1'.

Referring particularly to the accompanying drawings, 10 represents aportion of a tank, which is adapted to contain the liquid to bedispensed. .Formed integrally Awith the lower portion of the side wall-.of the tank,.and projecting outwardly therefrom, is anipple 11, andVformed on the lowerside of the outer en d portion of the nipple is a-downwardly and outwardly inclined spout 12. In thecenter of the'outerend wall of the nipple'there isvformed A.an opening 13.

' Inthe surrounding-wall of the inner end of the 'pple, or where'the'bore thereof enters the tank, there is formed-a boss 14.

@langem Openings -18 Slidable in the' bore of the nipple is ahollowcylindricalcharge measuring member 15, the' inner end of which is formedwith a' beveledhead 16 arranged 'to seat against the boss 14, when thesaid member is in its outermost position. In the wall of the member r15,adjacent the head 16, are the elongated longitudinally extendingopenings 17, whlle -circular opening are formed in said relates to newand useful member a' 'suitable distance outwardly'of the i openings 17,but extending circumferentially of the member. These openings 17 and 18are spaced short distances from each other, so that each circular seriesof openings is, in effect, an opening or slot, extend- 'V ing completelyaround the member', whereby to facilitate the entrance of liquid fromthe tank, into the member, and also to facilitate the dischargetherefrom into the spout 12.

.Both'ends of the cylindrical member 15 are the same being held inposition on the .stem

by means of theterminal nut 21. Encircling the stem, and bearing againstthe said collar 20, and the Aend wall of the nipple, is a coil spring22, which normally urges the cylindrical member outwardly, so that itsopenings 18 are in registry with the inner endof the spout 12. Mountedonthe outer end of the nipple is a bracket 23, andsupported on thisbracket, at one side of said nipple, is. aA holder vfor sanitary pa 'ercups, said holderibeing designated by t e numeral 24. Thisholder isprovided with an operatingl arm 25, projecting transversely of the outerendof the nipple, for causing the single delivery ofvthe\-paper.cups.Mounted on the bracket 23, at the other side of the nipple, is ahorizontally disposed table 26, said ltable having a longitudinal slot'27 formed therein, Yandat, the forward end of said table there isformed .fa comparatively small 28. Secured to the lower face ofthe table26, and spaceda short dis- 33, and engaged'on the upper end' ofthe pinis the ongitudinally slotted ortion of a link 34, whileV thelongitudinally slotted portion of a similar-link is engaged on thelowerend .of the in. Extending vertically through the ta le and plate,.at

tance'therefrom, is .a plate 29; alsohaving Slidable longitudinallybetween mo i Y plate, both above and below thereof, is a pin 'side ofthe slots thereof, adjacent the nipple 11, is a pivot pin 36, andengaged on the upper portion of this pin is the vertical pivot portion37, of a lever 38, the other end of said lever being pivotally connectedwith the cup operating arm 25, by means of the link 39. On the lower endof the pin B6 is a centrally mounted rock lever 40 supported on thelower faceof the table is a rock lever 42, one end of which is pivotallyconnected with the other end of the rock lever 40, by means of the link43. The other end of the rock lever 42 is formed with a yoke 42', theends of the arms of which are engaged in the groove of the collar 20,for actuating the stem of the'cylindrical member 15, inwardly, the coilspring 22 serving to restore the stem to its outer limit of movement. ahand-grip 31.

The sliding movements of the plunger 31 ar'e adapted to be controlled bya detent mechanism, represented, as a whole, by the numeral 44, but notdescribed herein, as such details are fully set forth in my applicationfiled of even date herewith.

The plunger is adapted to be pushed inwardly whereby to operate thevarious levers and links, and accomplish the release of a drinking cup,and the operation of the liquid measuring cylinder, to receive itscharge of lliquid from the tank. Releasing the plunger normal outwardposition, by meansFo the spring 22, so as to register its openings 18with the spout, and discharge its liquid into the cup placed below thespout.

Mounted beneath the cup delivering mechanism is a chamber 54, theiifrontportion of which is open,/as/seen in the drawing, and formedinthe/bottom wall of this chamber is a cup VVreceiving recess 55. Inoneend of the upper wall of the chamber there is secured a downwardlytapering spout 56, to the upper end of which is properly secured adownwardly tapering spout 57, forming a part of the .cup mechanism.Leading downwardly, and laterally from the lower end of the spout 56, isa chute 58, in which the individual paper cups slide, to be seated, inan upright position in the recess 55. The lower end of the chute 58 issecured to the ladjacent side of the recess 55, whereby to On the outerend of the plunger is wall 59, against which the cup engages, and

the recess 55, directly beneath the liquid' spout 12, and then thecylinder 15 moved inwardly to receive `a charge of liquid from the tankand outwardly to deliver its charge into the waiting cup. In the, bottomof the recess 55 there is secured a drain pipe 60, to discharge anywaste accumulating in the recess, such waste being arranged to be caughtby any might be placed therebeneath.

In the center of the upper wall of the chamber there is formed anopening 61 through which the end of the spout 12 projects, to dischargethe liquid directly into the cup.

What is claimed is:

1. In a liquid dispensing machine, the combination with a measurin valveand a cup dispensing mechanism, o a support, a plunger slidable on thesupport, links operatively connected with the plunger, connectionslbetween one of the links and the measuring valve, and connectionsbetween the other link land the cup dispensingmechamsm.

2. In a liquid dispensing device, the combination with a measuring valveand a cup dispensing mechanism, of a guide vdisposed suitable receptaclewhich adjacent the valve and cup mechanism, a Y permits the cylinder 15to be restored to /plungerlmeunted/onthe"`guide, a pin carried by theplunger and extending, above and below the guide, a link connected withthe upper end of the pin and with the cup mechanism, and a linkconnected with the lower end of the pin and with the measuring valve.

3. In a llquid dispensing device, the combination with a measuring valveand a cup dispensing mechanism, of a support adjacent the valve andhaving a longitudinal slot therein, a plunger slidable in the support, avertical pin carried by the plunger extending below the plunger andupwardly through said slot, a link pivotally connected to the upper endof the pin above the support and operatively connected with the cupdispensing mechanism, and a link pivotally connected with the lower endof the pin and operatively connected with thc measuring valve.

In testimony whereof, I aix my signature.
